"God's truth! Where am I?" he exclaimed, and waved his sword in the sunlight.


[CHAPTER XXIV.]

MISTRESS AND ENEMY.

There had been two human obstacles to the advance of Gustavus Adolphus. One was George William, Elector of Brandenburg, whose fortresses of Custrin and Spandau, held by any one but Gustavus, were awkward things in the way of a retreat, if the Swede had to make one. George William was very averse to the Edict. Magdeburg was one of the pearls of his principality. But not being sure that Gustavus was strong enough to beat the Emperor, he shilly-shallied. Gustavus in his impetuous way had appeared at the gates of Berlin with a bodyguard of Swedes armed and trained to a fine point. George William saw them and hesitated no longer. Custrin and Spandau were lent to his friend Gustavus.

The advance of Gustavus southward was thus secured till he should come to the Elbe, and across fine flat country suitable for such a march. Once across the Elbe, he would be between Tilly and the Emperor. He would also be in Saxony.

But the obvious crossings of the Elbe were at the bridge of Dessau and the bridge of Wittenburg, both in the hands of the Elector of Saxony, John George.

John George had not made up his mind. He was an Elector of the Empire. He was also prince of a large territory. And the southern march of his lands was also the march of Bohemia, and the south-west was the upper Palatinate in the hands of Maximilian since the days of the Winter King. He was also averse to Edicts and in favour of the pure Gospel as represented by Lutheranism. But like the young man in the days of the founder of the original Gospel, he had great possessions.

Unlike his brother Elector of Brandenburg, he was not liable to a sudden nocturnal visit from the impetuous Gustavus, since a very large and populous country lay between, but, apart from such forcible persuasion, the policy of Saxony was not as yet to break from the Emperor. In the days of the Winter King he had refrained from joining in the mad escapades of the Protestants. He had no desire to do so now. Neither was he inclined to bow to the Edict. And to meet the urgent demands of the Emperor on that head, he had bethought himself of the strong man armed. He had armed accordingly. Through the kindly offices of Wallenstein, who was not unwilling to see the Saxons arming, he had been able to secure a good Lutheran general—one Arnim, who, like his old captain, Wallenstein, was without a command. The Elector of Saxony had forty thousand soldiers in spick and span new uniforms getting drilled by Arnim. But whether they would ultimately fight Gustavus, or merely grow fat and well-liking under the pay and treatment of Arnim, and never fight at all, John George was not at present sure.
